Wastewater analysis is widely applied internationally as a tool to measure and interpret drug use within national populations.

By gathering samples of a known source of wastewater scientists can estimate the number of drugs used in a community from the measured levels of illicit drugs and their metabolites excreted in the urine. 

EMCDDA has published the latest results of European multi-city wastewater analysis and drugs study.

The characteristics of European cities differ considerably; with some being major tourist or business hubs with varying day and night time populations. The results provide a valuable snapshot of the drug flow through the cities involved, revealing marked geographical variations.
